I worked at LinkedIn in Mountain View, CA and Palo Alto, CA, in 2004 and 2005.
At LinkedIn, I went back to a bullpen. We called it the "jungle" because of the decorations. It was very nice, with simple, open IKEA furniture and large cinema monitors for Macs.
This was the first office I worked in, in Mountain View, CA.
This was the second office I worked in, in Palo Alto, CA, in the former Paypal building.
And my commute took me over this pedestrian bridge every day, twice a day.
